  <background>
    <p>HAProxy is a TCP/HTTP reverse proxy for high availability environments.</p>
  </background>
  <description>
    <p>It was discovered that HAProxy incorrectly handled certain HTTP/2
      headers.
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker could send a specially crafted HTTP/2 header, possibly
      resulting in execution of arbitrary code with the privileges of the
      process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
